Serial certain new and useful Improvement in Apparatus forthe Manufacture of Glass, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l is a plan view, partly in horizontal section, illustrating my improved device and apparatus as adapted for use, in connection with a continuous tank furnace, in the manufacture of'glass; Fig. 2 is a side elevation, partly. in vertical section, of a part of the same, a casting table and casting pots being substituted for thedrawing k1ln and drawing pots; Fig.3 is a plan view of a casting table used in the manufacture of plate glass; Fig. 4 is a side elevation of the same; Fig. 5 is a vertical sectional view of a casting pot to be used in the manufacture of plate glassyFig. 6 is a vertical sectional view of a kiln and pot from which glass cylinders are drawn in the manufacture of' Window glass; Fig.1? is a side elevation of the apparatus or crane used in taking the molten glass from the tank furnace and transporting it to the place ofmanu'facture of the glass article; Fig. 8 is a plan view of the same; Fig. 9 is an end view o f the tongs, and the cam operating the aws of the same; Fig. 10 is a vertical sectional view showing the clutch and gear wheel that oscillates the arm of the crane; and Fig. 11 is a view showing the face. of the clutch.

My invention relates to the manufacture of glass articles, such as plate and window glass, and it consists in devices for support- .ing vessels containing molten glass in the heat of the tank furnace, and for dipping, lifting, carrying and depositing the vessels, which devices and apparatus are well adapted for use in connection with an improved method of manufacturing glass invented by \me and forming the subject matter of Let- 1 ters Patent No. 1,186,076, dated June 6, 1916,

this application being a substitution for my application, Serial No. 829,011, filed April 2, 1914. v In the drawing, 2 represents a continuous tank furnace for meltin the glass, in whi'ch furnace are shelves or enches 3 and 4 for holding the glass pots 5 and 6, the pots 5 vtank furnace, the glass will not chill, as is the case when the ordinary metal ladle is used, and the glass may be allowed to properly temper therein before casting. The pot 5 and the kiln 15 re shown enlarged in Fig. 6, and the pot 6 an the casting table are shown enlarged in Figs. 3, 4, and 5. In the sides and end of the furnace are doors 8 and 9 through which the pots 5 and 6 may be placed on and removed from the benches 3 and 4, the doors 9 being located at the dipping end- 10 of the furnace and the doors 8 being at the melting end 11, the division being at the floaters 12.

At the sides of the furnace and running to being connected by suitable mechanism with the driving wheel. 24 of the car. Mounted on the car 17 is a base plate 28 on which is a hollow revoluble pedestal 29 at the base of which ithe annular worm 30 which is driven by a motor 31 through a gear wheel 32 and a worm 33. Fitting in the pedestal 29 is the vertical cylinder 34 which is internally threaded but is prevented from turning independently of the pedestal 29 by the vertical keys 35 which extend from the outer face of the cylinder and fit within vertical ,splines in the interior face of the pedestal 29. Within the cylinder 34 is. a screw 36, the thread of which engages with the thread of the cylinder, and it is driven by means of a worm wheel 37 and a worm 38 which is soconnected by suitable mechanism with the double clutch that by throwing the lever 27 ing being provided with a screw thread 41,

and two splines or keyways 42 for the reception of feathers or keys 43 extending inwardly from; the clutch 44, thus providing 7 .means' to keep the shaft 40 from turning on -ment being imparted to the shaft.

its axis when the clutch 44 engages with the slots 44 in the head 39' of the housing 39,

"permitting, however, a reciprocatinq'moveflhis reciprocating movement is imparted to the shaft 40 by means of a wheel provided with a worm gear on its periphcry and a screw thread in its hub, which screw thread meshes with the thread 41on the shaft, so that by the rotation of the wheel 45 the shaft, held from rotation, is caused to move longitudinally. Power is imparted to the gear wheel 45 by means of a worm 46, thegear wheels 4? and 48 and .the motor 49. On the face of the wheel 45 are clutch lugs 45 adapted-to engage in recesses in the face of the clutch i4, when the clutch is thrown forward by the lever 41,

' and thus rotate the clutch and turn the shaft Within the bore 50 of the 'hollow -shaft 40 is a rod 51 provided at one end with a hand-wheel 52 and at the other end with. a cam 53 which engages with the short arms 54 of a pair of tongs which are pivoted at 55 to a bracket 40 secured to the end of the shaft 40, the jaws 54 of which tongs are adapted to engage with the recesses 23 of the pots, and these jaws are normally held open by the spring 56. All the motors of this crane are started and reversed by the multiple controller 57 operated by the levers 58, the current being. received by the trolley 59.

The operation of my improved apparatus is as follows: In the manufacture of window glass, the batch of sand and alkali is fed into the melting end 11 of the tank furnace,

where it is melted by gas from the regenerative fiues 21, and the molten glass flows beneath the floaters 12 to the dipping end 10. On some of the benches 4 are the pots 5 or t 6,- which are there placed to be heated to a high degree of temperature from the heat of the furnace preparatory to the dipping of the glass.

After the pots have been sufliciently heated, the trolley car 17 is run to the side of the furnace opposite one of the doors 8.

The arm 40 of the crane being in its re- .,tracted position and the jaws of the tongs at the end of the rod 51 being extendedunder the force of the spring 56, the tongsare swung toface the door by means of the motor 31, the' worm-wheel 30 and the worm 33. The tongs are then advanced to a position where an arm of the tongs is on each side of a pot, which is done by the motor 49, the worm 46, the worm wheel 45 and the screw 41, and then the-jaws of the tongs are caused to grasp the pot in the recess 23 by giving the hand wheel 52 a half turn which causes the cam 53 on the end of therod 51 to force open the arms 54, thus closing the jaws 54.

Thev arm 40 carrying the pot, is then; raised by the screw 36 turning in the threadsof the cylinder 35 extending from the housing 39, power being imparted to the sciew' by means of the motor 25, the worm 38 and worm wheel 37, and the clutch 26 which is operated by the levers'27.

The arm 40, carrying the pot, is thenrevtracted and swung to its former positlon, the car is run in front of the door 9, as shown in Figs. 1 and 2 and the pot-is filled by dipping it'into the molten glass by lowering the arm 40, the'motor 25ibe1ng operated in' the reverse direction from that described, and by tilting the pot, which 1s done by imparting a rotary movement to the shaft or arm 40, which is accomplished by throwing the clutch 44 in contactwlth the wheel 45 and. starting the motor 49.' Afthe molten glass in the tank furnace, it is sky ter the side of the pot is below the level of righted by reversing the motor 49, lifted above the level of the glass in the furnace,

the car is again run to one of the doors and the pot containing the molten glass is placed on one ofthe benches 4 where it is al-* lowed to remain in the heat of the tank furs carried to a casting table where the ot may.

be tilted and the molten glass. poure on the table.

glass in-the pot has From the foregoing description those skilled in the art should be able to appreciate the advantages of my invention.

Although I have shown and described electric motors, worm gears, and .other power imparting mechanism, I do not desire to limit myself thereto, as equivalent devices, which suggest themselves to those skilled in the art, may be substituted therefor without departing from my invention.
